CiscoDP may be used to communicate VLAN information to an attached IP Phone, when configured as shown below.
set ciscodp state enable
set ciscodp timer 10
set ciscodp port status enable vvid
The reduced timer setting is so that the phone will know of its intended VLAN before it attempts DHCP. It will thus specify the proper VLAN in its 802.1Q tags, for all its communication. The untagged data from any phone-attached PC will be unaffected by this configuration, and will use the port's PVID setting for its VLAN assignment.
For more CiscoDP configuration options, please refer to the Configuration Guide.
